The first thing to understand is why people blink. Blinking is an instinctive human action and is a normal physiological activity of the eye muscles. Reflexive blinking occurs when a person feels uncomfortable or nervous such as dry eyes or astringent eyes, and these are normal muscle activities. Blinking is a protective mechanism that protects the eyes from foreign objects and light stimulation, and also ensures that tears are evenly distributed to protect the cornea, avoid dryness of the eye surface, and prevent dust damage. Newborns blink 2 times per minute, and when they grow up, the number of blinks normally reaches 14-17 per minute. If the number of blinks greatly exceeds this frequency, it is pathological. So what are the common causes and treatments for frequent blinking in children? 1, dry eye syndrome Previously, living conditions were limited, TV watching less, very few children dry eye, now a variety of cell phones, game consoles, learning machines and iPads, become poison for children. Image stimulation, TV screen flickering, the speed of change, not only lead to children’s visual center over-excitation, but also make the child transient eyes reduced, resulting in easy dry eyes, after a period of time will eventually appear to start blinking more. Close the eyes to rest will improve, more contact and interaction with the child, to avoid the child and the machine for a long time to communicate. If it still does not improve, then you need to go to the ophthalmology department. 2. Allergic conjunctivitis Some children blink seasonally and often rub their eyes at the same time, complaining of itchy eyes, foreign body sensations, and sometimes seeing mucous-like secretions and poor results with antibiotic eye drops. Allergic conjunctivitis should be highly suspected at this time, and can be confirmed if there are also symptoms such as sneezing, runny nose or an itchy throat. Careful parents may also notice a lot of “bumps” on the inside of the child’s eyelids. This is caused by the child’s allergy to certain substances, such as pollen, dust mites, etc. Antibiotic treatment will not only not improve, but sometimes aggravate the symptoms. Anti-allergy eye drops such as sodium cromoglycate drops or pyrimethamine potassium drops should be used. In severe cases, topical hormonal eye drops should be prescribed by an ophthalmologist and closely monitored clinically. At this time, children should avoid rubbing their eyes, and ice water can be used to wash the eyes to reduce the symptoms. 3. Infectious diseases such as conjunctivitis and keratitis may be related to bacterial, viral or chlamydial infections, and are mostly related to the child’s poor hygiene habits and frequent rubbing of the eyes with dirty hands. In addition to increased blinking there are also manifestations such as: red, itchy eyes, increased secretions, and tearing. For frequent blinking caused by bacterial inflammation, use levofloxacin eye drops or tobramycin eye drops 3-6 times a day, and antibiotic eye ointment such as erythromycin to coat the eyes once a night. In severe cases, the number of eye drops can be increased to once every 1-2 hours. If the inflammation is caused by a virus, use ganciclovir or antabuse eye drops to spot the eyes 4 times a day. Systemic treatment is usually not necessary. Different infections may behave similarly, and parents who cannot distinguish between them are best advised to visit an ophthalmologist and ask for a prescription. 4. Congenital entropion and inverted eyelashes Some children have congenital entropion of the eyelids (medically called eyelids) or obesity that causes the eyelashes to fall back on the surface of the eye, irritating the cornea (the surface of the black eye) and causing tearing. This condition is most common in lower eyelids and can be detected by attentive parents. In mild cases, the eyelid can be gently turned out to its normal position and fixed by traction with tape on the local skin. In severe cases, surgery is required to correct the problem. 5, eye fatigue blink including vision fatigue, such as refractive error, especially farsightedness, myopia, astigmatism not corrected resulting in eye visual fatigue and caused. This is a protective reflex, by constantly blinking can adjust the curvature of the eye, so that visual clarity. In this case, you should arrange your child’s school life appropriately, tell your child that the time spent reading books and watching television and computers should not be too long, urge your child to do eye exercises, and if necessary, get an eye exam and glasses. 6. Habitual blinking Some children have a history of frequent blinking due to one of the above causes, and through treatment, after the cause is removed, they still retain the habit of blinking frequently. Other children, because they don’t usually pay attention, like to imitate other people’s frequent blinking, resulting in habitual frequent blinking. Parents should promptly remind their children to help them control themselves. 7. Temporary tic disorder This condition is generally nothing to worry about, as 4% to 24% of school-age children have this condition, with involuntary eye muscle twitching, related to stimulation and stress, learning or mood discomfort. Sometimes the symptoms go away when the child is in a different environment, such as when you take him to the doctor. This condition usually subsides on its own, in about 1 month. If the child has had this condition for more than a year and has irritability, personality changes such as frequent strange noises, even cursing and swearing, this condition is medically called hyperactive obscene language syndrome in children. This disease seriously affects the normal life, learning and mental health of children. You should go to the pediatrician in a timely manner and cooperate with the doctor for treatment. Do not reprimand and scold your child, but gradually induce and patiently persuade him/her. In conclusion, there are many causes of frequent blinking in children, and treatment varies, requiring diagnosis and treatment by an experienced doctor. Parents should seek medical attention as soon as they notice their child blinking frequently to avoid aggravation of the disease. As long as they are detected and treated in a timely manner, the results are generally good. In addition, some more foods that are good for the eyes can be introduced, so you can selectively give your child some to eat in general. 1, carotene: can be converted into vitamin A in the body, carotenoid-rich foods are carrots, tomatoes, various green vegetables, as well as animal liver, cream, whole milk, egg yolk, etc.. 2.Vitamin B1: can be taken from brown rice, flour and various kinds of beans consumed daily. 3, vitamin B2, B6 natural food sources are animal liver, milk, egg yolk, peanuts, spinach, etc. 4, vitamin C: from a variety of fresh vegetables and fruits can be obtained. 5.Myopia prevention needs to start with infants and children. According to scientists, the occurrence of myopia is related to the lack of a trace element of chromium and calcium in the body. If a child eats a lot of sugar and high-carbohydrate food, it will reduce the body’s stores of the trace element chromium, and eating too much overcooked protein-based food will cause abnormalities in the body’s calcium metabolism, resulting in calcium deficiency. Therefore, to prevent myopia, in addition to paying attention to eye hygiene, we must also cultivate reasonable eating habits, pay attention to nutritional hygiene, eat less candy and food containing high sugar, eat less white rice and white flour, eat more brown rice and coarse flour, eat less lard, and limit the intake of high-protein animal fat and refined sugar foods to reduce the excretion of chromium in the body. At the same time, eliminate the baby’s poor eating habits of partiality, and eat more animal liver, eggs, milk, shrimp, beans, lean meat and grated roux.
